cLabs | San Francisco, Berlin, Buenos Aires, and Remote | Hiring Security Engineers, Data Engineers, Dev-Rel Engineers, Product Managers, Cryptographers, SRE/Infra and Mobile Engineers | All Levels | FULLTIME, ONSITE, REMOTE, INTERNS, VISA | https://celo.org

cLabs is one of a number of companies working on Celo, an open-source permissionless platform that makes financial tools accessible to anyone with a mobile phone. Using a novel decentralized PKI, Celo lets you send cryptocurrency to phone numbers in a fully decentralized way. Additionally, Celo uses stable-value tokens pegged to fiat currencies, like the US Dollar, to minimize volatility, and crucially allows transaction fees to be paid with these tokens. To make sure that the platform is scalable and fast enough for day-to-day use, Celo uses a new Proof-of-Stake protocol with fast block times and one block finality. Further, it uses SNARK-based proofs to allow light clients to sync with the chain near instantly. The protocol is now live (run by hundreds of entities) and we are now working with organizations such as the Grameen Foundation on an open-source social payments app (Valora) that looks and feels like Venmo, yet is fully decentralized. Celo is listed on Coinbase and many other reputable exchanges.

Backers: Andreessen Horowitz (a16z), Polychain, General Catalyst, Coinbase, Reid Hoffman and Jack Dorsey, among others.

Stack: Typescript, Solidity, Go, React Native, Python, Android, iOS, Rust, zk-SNARKs
